I am not politically a proponent of the death penalty. That said, the all or nothing ideological viewpoints held in political circles, (yes, even my own), do not fit this case.
Torture is far worse than death, and I will never support that. He deserves the worst possible punishment, short of inflicting a lifetime of torture. Solitary confinement is torture. If someone is seriously being considered for this type of punishment, they have exceeded the threshold of what I would consider an allowable case for the death penalty. The death penalty is the only logical solution.
Society has no use for sub-human homo sapiens such as Tsarnaev.
